What are the zeros of the quadratic function f(x) = 6x ^ 2 - 24x + 1 ?

ZanzabumX [31]

Answer:

x = $\frac{12+\sqrt{138} }{6}$ and x = $\frac{12-\sqrt{138} }{6}$

Step-by-step explanation:

Let's use the quadratic formula, which states that for a quadratic of the form ax² + bc + c, the zeroes are: $x=\frac{-b+\sqrt{b^2-4ac} }{2a}$ or $x=\frac{-b-\sqrt{b^2-4ac} }{2a}$ .

Here, a = 6, b = -24, and c = 1. Plug these in:

$x=\frac{-b+\sqrt{b^2-4ac} }{2a}$

$x=\frac{-(-24)+\sqrt{(-24)^2-4*6*1} }{2*6}=\frac{24+\sqrt{552} }{12}=\frac{24+2\sqrt{138} }{12} =\frac{12+\sqrt{138} }{6}$

AND

$x=\frac{-b-\sqrt{b^2-4ac} }{2a}$

$x=\frac{-(-24)-\sqrt{(-24)^2-4*6*1} }{2*6}=\frac{24-\sqrt{552} }{12}=\frac{24-2\sqrt{138} }{12} =\frac{12-\sqrt{138} }{6}$

Thus, the zeroes are: x = $\frac{12+\sqrt{138} }{6}$ and x = $\frac{12-\sqrt{138} }{6}$ .

The temperature last Monday was 32˚F at 8:00 am. During the next hour it dropped to 24˚F. What was the percent decrease?

jek_recluse [69]

Answer:

The percentage decrease in the temperature is 25%.

Step-by-step explanation:

The temperature last monday was =32°F

The dropped temperature during the next hour=24°F

The Percentage decrease in the temperature will be= $\frac{32^{{\circ}}-24^{{\circ}}}{32}{\times}100$

= $\frac{8}{32}{\times}100$

= $0.25{\times}100$

= $25%$

All you have to do is divide 150 by 18 and that will get you how many meters Pete drives per second

150 ÷ 18

8.3333333333333333333

so...

8.3 m/s (B)

Hope this helped!
